Rodents are the natural hosts for Leptotrombidium mites that transmit Orientia tsutsugamushi, the causative agent of scrub typhus, a potentially fatal febrile human disease. Utilizing mite lines that included O. tsutsugamushi infected and non-infected Leptotrombidium species we investigated the varied infection response of outbred mice (ICR) exposed to L. chiangraiensis ...

Serotonin is produced by pulmonary arterial endothelial cells (PAEC) via tryptophan hydroxylase-1 (Tph1). Pathologically, serotonin acts on underlying pulmonary arterial cells, contributing to vascular remodeling associated with pulmonary arterial hypertension (PAH). The effects of hypoxia on PAEC-Tph1 activity are unknown. We investigated the potential of a gene therapy approach to ...

MATERIAL AND METHODS: We analysed plasmatic and hepatic drug concentration in four groups of six mini-pigs each according to the modality of administration of CDDP ...

Dendrites of nerve cells have membranes with spatially distributed densities of ionic channels and hence non-uniform conductances. These conductances are usually represented as constant parameters in neural models because of the difficulty in experimentally estimating them locally. In this paper we investigate the inverse problem of recovering a single spatially ...

The spatial organisation of the splicing system in plant cells containing either reticular (Allium cepa) or chromocentric (Lupinus luteus) nuclei was studied by immunolabelling of SR proteins, snRNA, and the PANA antigen, known markers for interchromatin granule clusters in mammalian cells. Electron microscope results allowed us to determine the distribution ...

Nightmares are intense, emotionally negative mental experiences that usually occur during late-night sleep and result in abrupt awakenings. Questionnaire-based studies have shown that nightmares are related to impaired sleep quality; however, the polysomnographic profile of nightmare subjects has been only scarcely investigated. We investigated the sleep architecture of 17 individuals ...

Sustained release of copper (Cu) ions from Cu-containing intrauterine devices (CuIUD) is quite efficient for contraception. However, the tissue surrounding the CuIUD is exposed to toxic Cu ion levels. The objective for this study was to quantify the concentration dependent cytotoxic effects of Cu ions and correlate the toxicity due ...

Highly sensitive detection of proteins offers the possibility of early and rapid diagnosis of various diseases. Microchip-based immunoassay integrates the benefits from both immunoassays (high specificity of target sample) and microfluidics (fast analysis and low sample consumption). However, direct capture of proteins on bare microchannel surface suffers from low sensitivity ...

The epigenetic mechanisms of HCV-induced hepatocyte transformation towards malignancy in this context are unclear. AIMS: The purpose of this study was to evaluate the effect of HCV core proteins of different genotypes on ...

Lifestyle intervention programmes often produce insufficient weight loss and poor weight loss maintenance. As a result, an increasing number of patients with obesity and related comorbidities undergo bariatric surgery, which includes approaches such as the adjustable gastric band or the 'divided' Roux-en-Y gastric bypass (RYGB). This Review summarizes the current ...

A series of polyclonal antibodies generated in vivo using BPA-butyrate-protein conjugate and BPA-valerate-protein conjugate were evaluated on direct and indirect competitive assay formats with ...

BACKGROUND: In the absence of reliable, objective and direct measures of awareness, the diagnosis and prognosis of the vegetative and minimally conscious states are greatly complicated. This has led to an unacceptably high level of misdiagnosis. Although diagnosis and prognosis have typically relied on bedside behavioural measures, a number of ...

When trauma patients are transferred from outside hospitals, the receiving clinicians often consult their local radiologists for definitive interpretations of outside examinations (IOE). Such requests introduce a host of logistical, medicolegal, and financial concerns related to quality control and resource utilization. We surveyed 701 members of the American Society of ...

Platinum nanoparticles (PtNP) exhibit remarkable antioxidant activity. There is growing evidence concerning oxidative stress and bone loss suggesting that PtNP could protect against bone loss by modulating oxidative stress. Intragastric administration of PtNP reduced ovariectomy (OVX)-induced bone loss with a decreased level of activity and number of osteoclast (OC) in ...

In mammalian peripheral nerves, unmyelinated C-fibers usually outnumber myelinated A-fibers. Using transmission electron microscopy we recently showed that the saphenous nerve of the naked mole-rat (Heterocephalus glaber) has a C-fiber deficit manifested as a substantially lower C:A-fiber ratio compared to other mammals. Here we determined the uniqueness of this C-fiber ...

The treatment of open distal tibia fractures remains challenging, particularly when the fracture is infected and involves segmental bone loss. We report the case of a 38-year-old man who sustained an open distal tibiofibular fracture with segmental bone loss and a closed proximal tibial fracture. The fractures were initially fixed ...

Sintered cancellous bovine bone (SCBB) offers numerous advantages as a bone graft substitute material; however, its mechanical properties require improvement. In this study, SCBB was infiltrated with ε-polycaprolactone (PCL) or chitosan/monetite to improve mechanical properties while retaining valuable SCBB structure. Organic infiltrating solutions consisted of (i) chitosan and monetite (CaHPO(4) ...

BACKGROUND: Radical rectal resection with total mesorectal excision is the current standard of care for the operative treatment of rectal cancer. Local excision is an acceptable alternative in selected patients with early disease (T(is)0-T(1)) and low-risk features, in whom radical resection may be associated with unacceptably high morbidity. With recent ...
